Mirabilla Warenne, daughter and heir of Reginald Warenne, late lord of Kilgraston, and Robert, her son and heir, have given, granted and by this their present charter established to Sir John of Muncref, of the third part of their heritable right in the mill of Kilgraston (PER). They are to render three cloves (clavos de Gelofyr) at the fair of Dundee for all secular service, demand and every exaction pertaining the third part of the mill. Mirabilla and Robert promise warrandice, and penalties are stipulated for failure to comply with the aforesaid.
Of the witnesses mentioned, Sir William of Moray does not appear to have been knighted until about 1284. Master Alpin, Official of St Andrews, was probably the same as the Master Alpin who was Treasurer of Scotland in 1293, and if son would presumably have held the minor office of Official before he became Treasurer. This would make the two limiting dates 1284-1293. Reginald de Warrenne was dead by 1247, and Sir Nicholas of Hay died between 31 May and 3 September 1305 (see _Moncreiffes_, ii, p. 640).
